Using The Extron Expansion Bus With Dmp 128 At Devices; Viewing At Channels With At Meters - Extron electronics DMP 128 User Manual

Using the Extron Expansion Bus with DMP 128 AT Devices
A DMP 128 AT model can be connected to a non-AT model by the Expansion (EXP) ports
with the following exceptions:
•
•
•
•
DMP 128 AT devices are set as the Primary unit by default. This setting cannot be changed
because the expansion bus primary and secondary selections in Device Settings are not
available on AT models (see

set as the secondary unit.
To configure Expansion port connectivity using a DMP 128 AT:

Configuration of the EXP channels can be done at this time. You can also add additional AT
models to the digital audio network. Always make the Expansion port connection between
the two units before adding AT units to the digital audio network (see
Audio Setup
NOTE: The Dante Controller software is required for configuration of the AT expansion
When connected to a non-AT device, all 56 receive channels of the DMP 128 AT still
appear on the Dante digital audio network. However, Expansion inputs 41 through 56 are
connected to the secondary (non-AT) device by the EXP bus, and are not operational on the
Dante audio network.

Viewing AT Channels with AT Meters

The AT meters allow the user to see the signal levels of any attached Dante device. See
View menu
A connected Dante device is selected and all active transmit and receive channel real-time
signal levels for that device are monitored.
Two AT models cannot be connected together using their EXP ports.
AT models are always the primary unit. The non-AT model must be set as the secondary
unit.
The sixteen EXP outputs from the non-AT secondary unit connect to the AT primary unit
at inputs 41 through 56.
The secondary DMP 128 or DMP 128 C EXP inputs are routed as they normally would
be.
